Ecology and Species Interactions

The video explains the concepts of species, population, and community using lions as an example. It describes the global distribution of lions, focusing on the Sangti National Park in Tanzania. The video defines species as a group of organisms that can interbreed, population as individuals of the same species in a specific area, and community as diverse populations interacting in an environment. It concludes with a summary of these ecological concepts.

What is a species?

• A group of organisms that can interbreed and produce viable offspring

• A single organism with unique characteristics

• A group of organisms living in the same geographical area

• A mix of different species living together

Where are Asiatic lions primarily found?

• In the Kir forest in India

• In the Australian outback

• In the Amazon rainforest

• In the African plains

What defines a population in ecological terms?

• A group of organisms that cannot interbreed

• A single organism in a habitat

• A group of individuals of the same species living in a specific area

• A group of different species living together

How many lions are estimated to be in the Sangti Mara ecosystem?

• 4,000

• 3,000

• 2,000

• 1,000

What is a community in ecological terms?

• A group of organisms that cannot interbreed

• A group of populations of various species living and interacting in a specific environment

• A single species living in an area

• A single organism with unique characteristics

Which of the following is NOT a species that interacts with lions in the national park?

• Penguin

• Deer

• Zebra

• Cheetah

What is the primary focus of a community in an ecosystem?

• The physical characteristics of a single organism

• The genetic diversity within a species

• The interactions between different populations of various species

• The number of individuals in a population

Which of the following best describes an ecosystem?

• A community of organisms interacting with each other and their environment

• A single organism with unique characteristics

• A group of populations of the same species

• A single species living in isolation

What is the relationship between species, population, and community?

• Species form populations, and populations form communities

• Species are groups of populations, and communities are groups of species

• Populations are groups of species, and communities are groups of populations

• Species are larger than populations, which are larger than communities

Which of the following is a key characteristic of a species?

• Living in the same geographical area

• Interbreeding to produce viable offspring

• Competing for resources

• Interacting with other species
